Siemens 3TA2112-0A Contactor

Siemens 3TA2112-0A Contactor is a power switch rated for 16 A at 600 VAC on a three‑phase load. It uses a six‑pole main circuit and includes two normally open and two normally closed auxiliary contacts to support signaling and interlocking in control circuits. As part of Siemens’ 3TA family, it is designed to reliably switch three‑phase motors and other AC loads in industrial control panels, with applications in conveyors, pumps, and fans where compact, robust motor control is needed. The auxiliary contacts simplify integration with control logic and feedback for automation sequences, allowing interlocks and status signaling without adding separate components. This model is well-suited for panel builders and OEMs seeking a durable, space‑efficient contactor for 3‑phase equipment up to 16 A at 600 VAC, backed by Siemens’ engineering and compatibility within the 3TA lineup.
